Payward, the parent company of cryptocurrency exchange Kraken, has joined Anthropic's Project Glasswing, gaining restricted access to Claude Mythos 5 for defensive cybersecurity work. The company plans to use the artificial intelligence model to scan its software environments for vulnerabilities over the coming weeks. Findings will enter Payward's existing security review process rather than automatically producing software changes. Payward also intends to disclose validated vulnerabilities affecting third-party open-source projects to their maintainers.
Security Review Process
The company's infrastructure supports digital asset trading, custody, and settlement services that remain available continuously. However, the announcement does not specify whether Mythos 5 will receive access to production systems, isolated copies of source code, or controlled testing environments.
Artificial Intelligence in Security
Payward co-chief executive Arjun Sethi said AI could change the imbalance between attackers and defenders by reading code at greater scale. 'A model can read every line of code the way an attacker would, at machine scale, so we find the flaw before anyone can build the exploit,' Sethi said.
Project Glasswing
Anthropic launched Project Glasswing in April 2026 to give selected infrastructure providers and software maintainers early access to its strongest cybersecurity models. The company says participating organizations must meet security requirements before receiving access. Mythos 5 is not generally available because the same capabilities used to identify vulnerabilities can also help produce working exploits.
